Highly efficient new indoline dye having strong electron-withdrawing group for zinc oxide dye-sensitized solar cell
摘要:
New indoline dye (DN319) having strong electron-withdrawing dicyanovinylidene moiety and octyl group in the terminal rhodanine ring gave higher efficiency than D205, which was known as an excellent organic dye sensitizer. This result is attributed to the bathochromic shift in the UV-vis absorption band and positive shift in the E-ox level of DN319. (C) 2011 Elsevier Ltd. All rights reserved.

(2R,3aR,8bR)- and (2S,3aS,8bS)-2-Methyl indoline dye tetrabutylammonium carboxylates exhibited the highest conversion efficiency among four regio and stereo isomers. These indoline dyes also showed higher conversion efficiency than DN350.
A new indoline dye in which a double rhodanine acceptor is attached to the indoline moiety by a p-phenylene spacer on the indoline-nitrogen, has been examined for its performance as a sensitizer for zinc oxide dye-sensitized solar cells. In the presence of cholic acid, chenodeoxycholic acid, or lithocholic acid: the performance was greatest for lithocholic acid as this showed the greatest reduction in dye H-aggregate formation.
